SINGAPORE - A woman was jailed for four weeks on Monday (June 6) for conspiring with a man to pose as her ex-boyfriend to register a marriage.

The woman - a 32-year-old finance assistant - is not named to protect the identity of her young son.

She had admitted to abetting one Matthew Yeo Chia Loong, 32, to cheat Ms Michelle Leong Ton, a licensed solemniser, into believing that Mr Yeo was another man - her ex-boyfriend, whom she wanted to marry. Ms Leong then signed a certificate of marriage between the other man and the woman, on Oct 25, 2012.

The finance assistant had also pleaded guilty to abetting Mr Yeo to lie in a statutory declaration at the Registry of Marriages - that he was someone else - to register the marriage.

A district court heard that the woman was married in 2010 but not living with her husband. She met another man and they entered into a relationship.

During this time, she gave birth to a boy. Her husband was stated as the boy's father in his birth certificate. They divorced some time in 2011.

The following year, the boyfriend suspected that boy was not his son, and broke up with her despite her insistence that he was the child's father.

The woman then committed the offences as she was unhappy and wanted the man to return to her and not marry anyone else, said Deputy Public Prosecutor Chew Xin Ying.

So she decided to register her marriage to the ex-boyfriend without his knowledge. To do this, she secretly got hold of his identity card.

DPP Chew said on Oct 3 in 2012, the woman filed a notice of marriage on ROM's website and chose Oct 25 the same year as her solemnisation date.

She then asked Mr Yeo to help her impersonate her ex-boyfriend and sign the marriage certificate. Mr Yeo, who was married, agreed to help her.

Both went to the ROM on Oct 25. Mr Yeo then forged the woman's ex-boyfriend's signature before a commissioner of oaths who issued them the certificate of marriage.

On Nov 7, 2012, the ex-boyfriend lodged a police report stating that the woman had sent him a photo of a certificate of marriage containing his and her names.

Defence lawyer Diana Ngiam said her client was suffering from acute stress reaction at the time which led her unfortunately to commit the offences. She said her client had attempted suicide after the break-up.

She said her client is very sorry. The woman could have been jailed for up to three years and fined on each charge.
